Hi Miguel,
For some reason this stuff is quite difficult to find out. I am now quite happy with GC training mode, so I'll tell you what worked for me running a Wahoo Kickr from a PC via BLE (blue tooth light.)
First, I am not personally familiar with any of your devices so I am just telling you the general stuff. I connected to all my stuff from a PC using BLE. For that to work I obtained a Bluetooth 4.2 dongle off amazon and a long cord so dongle was near the exercise gear and away from the electromagnetic noise of the PC. Without this I had trouble connecting.
1) Turn off/disable any devices (phones) that you previously used to connect to your exercise gear. You don't want your old connections interfering with the new ones you wish to create.
2) Turn on all your exercise devices, get everything ready to connect, put on your heart rate monitor so it turns on and is broadcasting a signal.
3) Start golden cheetah, go to Tools/Options then click the 'training' tab on the far right.
4) Click the tiny '+' in the lower right of the 'train devices' tab. Choose device type, etc. You want to choose ANT+/FE-C which will take you to the 'Add Connection Wizard'. You need to have all your devices active so that they all show up here. You will create a single profile that knows how to connect to them all.
5) In training view click the round power button looking thing. It should change color to Yellow. At this point you should be seeing numbers displayed (heart rate, power, etc.)
6) Walk before you run: get a simple erg file from internet and get it working with your gear in trainer mode. Select the workout, hit the 'play' button. If everything goes well you should start getting resistance according to the workout.
7) I never had a very good time with the 'create workout from ride' feature, they just never felt right, the charm was lost for me. But I am super duper happy using RLV files I downloaded from internet. The video sync is amazing.
I hope this helps. Training mode is fantastic once you have it working.
